Embodiment 1
[0040] like figure 1 As shown, an embodiment of the present invention provides a loop detection method for a smart substation network, including the following steps:
[0041] S1. Obtain the configuration information and status information of each switch in the substation, and make a preliminary determination based on the configuration information and status information;
[0042] The configuration information includes an SCD file, and the status information includes the input rate and output rate in the logical node of switch port statistics and the port traffic alarm value in the logical node of switch traffic exceeding the limit.
[0043] Configuration information and status information can be obtained through IEC61850, which is a unified standard for smart substation network communication. The IEC61850 standard defines more detailed logical nodes and data objects, and establishes a complete dataobject model method and object-oriented service. Devices supporting the IEC618...
Embodiment 2
[0090] An embodiment of the present invention provides a loop detection device for a smart substation network, the device comprising:
[0091] The preliminary judgment module is used to obtain the configuration information and status information of each switch in the substation, and make preliminary judgment based on the configuration information and status information;
[0092] The secondary judgment module is used to obtain the SCD file of the substation and parse to obtain the physical topology of the substation, obtain the MAC address of each switch port and its connected equipment according to the physical topology, and perform secondary judgment based on the MAC address;
[0093] The final judgment module is used to continuously send ping request packets to each switch in the substation, obtain the ping response packets returned by each switch, and make a final judgment based on the number of ping request packets and ping response packets.
Embodiment 3

Abstract
The invention discloses a loop detection method and device for an intelligent substation network and a storage medium, and the method comprises the steps: obtaining the configuration information and state information of each switch in a substation, and carrying out the preliminary judgment based on the configuration information and state information; obtaining an SCD file of the transformer substation, analyzing the SCD file to obtain a physical topology of the transformer substation, obtaining MAC addresses of each switch port and equipment connected with the switch port according to the physical topology, and performing secondary judgment based on the MAC addresses; ping request messages are continuously sent to each switch in the transformer substation, ping response messages returned by each switch are obtained, and final judgment is carried out based on the number of the ping request messages and the number of the ping response messages; whether the loop exists in the intelligent substation network can be rapidly and efficiently detected.
Description
technical field [0001] The invention relates to a loop detection method, device and storage medium of an intelligent substation network, and belongs to the technical field of electric powerautomation. Background technique [0002] The smart substation network is the main carrier of the information exchange and sharing of the smart substation, and its safe and stable operation is the decisive factor for the stable and reliable operation of the power system. Due to the numerous network connection devices and complex network structure of the smart substation, in the engineering field, the engineering personnel often make wiring errors, which will lead to the formation of loops in the network and cause abnormal network communication. At the same time, in some engineering applications, the network structure adopts the ring network as the redundancy of the communication link, but the engineers often have the configuration error of the spanning tree protocol and the failure of the...
